Fancy Colored Diamonds

Diamonds come in various colors, most often caused by trace elements in the crystal lattice. Natural fancy colored diamonds are much rarer than white diamonds, especially combined with high clarity and carat size.

Except for black diamonds, all fancy colored diamonds from the house of A.P. Shaps are 100% natural and not treated in any way.

Pink Diamonds

Pink diamonds are extremely rare. 90% of the world’s supply of natural fancy pink diamonds are produced by only one mine and this mine will close at the end of 2020.

Like red diamonds, pink diamonds acquire their color from a structural defect called ‘plastic deformation’. This defect occurs when the rough diamond’s crystal lattice becomes twisted under extreme heat and pressure. Such an event causes specific wavelengths within the spectrum to absorb, and consequently, the color we perceive is pink or the more intense red.

Blue Diamonds

Blue Diamonds are among the rarest and most expensive natural diamonds.

They acquire their color from the trace element Boron, a rarely found pure element. The concentration of Boron molecules within the diamond’s crystal lattice impacts the tone and saturation of the blue tones and hues. Blue diamonds are formed at far greater depths than all other diamonds, approximately four times deeper than most other diamonds. Blue diamonds make up less than 0.0001 percent of the world’s diamonds.

Yellow Diamonds

Yellow diamonds are a family of colors of their own; they often come in overtones such as brown, green and orange. They are found less than one-thousandth of the time compared to white diamonds.

The color is caused by the trace element Nitrogen, which is commonly found in diamonds in which the crystal is categorized according to the presence or non-presence of nitrogen.

However, a fancy yellow diamond should not be confused with yellowish-white diamonds; a fancy yellow diamond must feature a clear yellow color to be counted as yellow and not towards the end of the white diamond color scale (D-Z)

Green Diamonds

Green diamonds are extremely rare and thus highly valued. The color ranges from light mint green to vivid lush green.

All other fancy colored diamonds acquire their color while they are still deep within the earth’s crust under tremendously high pressure and temperature either by impurities or deformation of the crystal lattice. However, green diamonds are unique in the sense that they acquire their color after reaching the earth’s surface when they reside in the ground near naturally occurring radiation.

Brown Diamonds

Brown diamonds, the most common color variety of natural diamonds, come in a wide range of colors and saturation, often including yellowish overtones.

Nitrogen, an impurity found in yellow diamonds, is responsible for the yellowish or brownish appearance.

A brown diamond also receives a large part of its unique color from the light absorbed through structural defects in the stone’s crystal lattice.

The brown color makes them less attractive as gemstones because of the reduced glimmer.  However, improved marketing tactics have led to brown diamonds becoming valued as gemstones and even referred to as chocolate diamonds.

Black Diamonds

Black diamonds, an impure form of polycrystalline diamond consisting of diamond, graphite and amorphous carbon, get their color from uncrystallized carbon (graphite) inclusions.

The diamonds are heat-treated to enhance the color and achieve a solid black color. The treatment is permanent because of the graphitization of the crystalline carbon.

Such treatment is only possible with diamonds containing a large number of inclusions (weak chemical bonding).
